“Apparently, from what we’re hearing — and we’re still in the initial investigation — is that … they were playing Russian roulette,” he said. “We don’t know that for certain, but what we’ll have to do is look at the evidence, along with some of the witness statements, and hopefully pull together exactly what occurred.

Blackmon said, late Tuesday afternoon, they were still gathering witness statements.
